This Smithsonian K-12 Education website provides a brief overview of mahogany tide (also known as red tide) events. These events are caused by dinoflagellates, a special type of phytoplankton, and can harm sea life. This website also features links to other related red tide sites. (less)

Toxic & Harmful Algal Blooms

Teaching unit investigates differences between toxic and non-toxic harmful algal blooms (HABs), where they occur in U.S. waters, causative phytoplankton species, technologies for detecting blooms, which organisms in the food web are affected and how, effects of specific toxins on humans. Five lessons contain: background and glossary; instructions for classroom and lab activities; online data; web links for further study. Lessons are aligned to teaching standards. (less)

This project provides a case study introducing students to patterns of relationships and evolution among economically important dinoflagellates, the causative agents of red tides. Using nucleotide sequences, students build a tree of relationships among dinoflagellate taxa. They use their tree (along with phylogenetic hypotheses derived from the literature) to explore the evolution of morphological and/or ecological characters in dinoflagellates. As broader applications, students learn to compare and evaluate hypotheses of evolutionary relationships. Additionally, because the case study focuses on dinoflagellates that have evolved toxicity, it can be used to further explore the biological and economic impacts of red tides. (less)
